SLEEPING-BAG.

SPECIFICATION forming part of Letters Patent No. 622,812, dated April 111899.

Application filed November 22, 1897. Serial N0. 659,401. (No model.)

To all whom it may concern:

Be it known that I, ADELARD LAPIERRE, a citizen of. the Dominion ofCanada, residing in the city and district of Montreal, Province ofQuebec, Canada, have invented certain new and useful Improvements inSleeping-Bags, (for which Canadian Letters Patent have been granted,dated February 3, 1898,'No. 58,914;) and I do hereby declare thefollowing to be a full, clear, and exact description of the invention,such as will enable others skilled in the art to which it appe rtains tomake and use the same.

My invention has relation to improvements in sleeping-bags.

The object of my invention is to provide a device of this characterwhich can be used in any climate, in all kinds of weather, and whichwill keep the user warm, comfortable, and free from contact with thedew, &c.

A further object is to provide a device which after the user has passedinside can be readily closed and fastened.

To these ends my invention consists in the improved construction andcombination of parts hereinafter fullydeseribed and particu larlypointed out in the appended claims.

111 the drawings, in which similar letters of reference indicate similarparts in all of the views, Figure 1 is a perspective view of my improvedsleeping-bag, showing the closingfiap as partially open. Fig. 2 is alongitudinal section of the same, showing the fiap in its closedposition. Fig. 3 is a cross-sectional View of the same.

Sleepingdoags for the use of persons exposed to the inclemency of theweather have been devised, but the varieties have been few andunsuccessful for the purpose desired. They have generally been formed insuch manner that the inlet of rain, snow, dew, &c., is not preventedexcepting to alimited extent, and those constructions are such as tomake them almost impossible to close after the user has placed himselfon the inner side of the bag. Another obstacle to the use of theabove-named construction is the fact that no mattress is provided whichcan be readily carried about, there being none such in which themattress forms a part of the bag.

To obviate these disadvantages, I have provided the sleeping-bag A,formed of some suitthe person using the bag passes inside. A

flap a, made of the same material as the bag, is secured at one sidethereof and is of sufiicient size to cover the opening aand extends tothe opposite side, where it is fastened. Secured to the under side ofthe flap, near its edges, are strips a provided with buttonholes orbutton-catches, as may be preferable, which button holes or catches areadapted to be fastened to buttons placed in position on the bag. By thisconstruction it will be apparent that when the occupant desires tosecure the flap he can readily do so by passing one hand between thestrip a and the flap a and fastening the buttons ontothe strip withoutbeing compelled'to place his hand out of the protection of the covering.

On the inside of the bag I place a suitable mattress a preferably an airmattress,which maybe secured to the bag, if desirable. The use of anair-mattress allows of the use of a light-weight material and makes thedevice one which is always ready for use and which can be folded into acompact form for transportation.

If desired, rods c of light materialsuch as steel, whalebone, &c.may beplaced in position, as shown in Fig. 3, to keep the top of the bag awayfrom the sleeper, said rods being located. at intervals along said bagand extending from one side to the other. It will be apparent that aseach rod a is mounted independently of the remaining rods and all therods being removable the position of the several rods may be changed asdesired. I may also, if essential, secure suitable airvents a in the bagat proper positions, by means of which the sleeper has at all times acurrent of fresh air introduced, preventing any danger of suffocation. Imay also provide an air-pillow, which may be secured to the bag asdesired.

It can be readily seen that by' the construction-shown the occupantisentirely independent of outside surroundings, the bag being capable ofuse in rain aswell as snow, there IOO being no liability of rain or snowpassing into the bag, there being no opening for its passage. This makesit a verydesirable article for the soldier, miner, frontiersman, gunner,&e., as it can be easily transported.

While the flap may be made as shown in Fig. 1, in which it is intendedto extend- 1. A sleeping-bag, comprising a compart ment; an opening atthe head end of said compartment; a flap secured to one side of saidbag. and extending over said opening to the opposite side thereof; meansfor securing said flap for removably securing said flap in posi= flap onsaid opening; whereby a closed com 20 partment will be formed; andair-vents leading to and from said compartment, substantially asdescribed.

2. A sleeping-bag comprising a waterproof compartment; an opening forsaid conipart- 25 ment at the top; a flap secured to one side of saidbag and extending over said opening to the opposite side of said bag,one side of said flap being adapted to extend over the end of said bag;and means, located beneath the 0 tion.

In Witness whereof I have hereunto set my hand in presence of twowitnesses.
